Burning eyes describes a feeling of burning and irritation of the eyes. Burning eyes can be accompanied by itching, tearing, or discharge from the eyes. Burning eyes have many possible causes. One of the most common is exposure to environmental pollutants such as tobacco smoke, smog, or dust. Chemicals found in household cleaning solvents, such as bleach, soap and shampoo, can lead to burning eyes. Chlorine in swimming pools can also make your eyes burn.
The Louisiana Purchase was an incredible deal for the United States, the final cost totaling less than five cents per acre at $15 million (about $283 million in today's dollars).
By its terms the Louisiana Territory, in the form France had received it from Spain, was sold to the United States. For this vast domain the United States agreed to pay $11,250,000 outright and assumed claims of its citizens against France in the amount of $3,750,000.
